Fig. 4

a The original input image which is divided into four separate parts for a parallel transmission along four independent channels (viz., Ch1, Ch2, Ch3, and Ch4 respectively). b The enlarged view of square region marked by red line in a. The two colors of pixel are encoded by binary information “0” and “1”. c The target and output data streams of four lines in b, marked by L1, L2, L3, and L4. d The output image reconstructed from four data streams received in real-time by four sensors located at focal points.
